Doing the math on paper for General Hydroponics Flora series nutrients was expert add-ons it says so many milliliters per gallon I added it up and and it says micro 82.5 ml grow 110 ml Bloom 27.5 ml root starter 27.5 that's for 11 gallons for just one week between 7 to 10 days then I'm supposed to change out can't it stay in there longer than just 7 to 10 days or am I going to be going through a lot of nutrients for one grow any input would help me make a decision
